The video was originally tweeted by White House Director of Social Media and Assistant to the President Dan Scavino before being retweeted by Trump.

In the video, Biden says, “Because we cannot re-elect … we cannot win this re-election … Excuse me, we can only re-elect Donald Trump.” The video cut the rest of what Biden said, “We can only re-elect Donald Trump if in fact we get engaged in this circular firing squad here. It’s gotta be a positive campaign, so join us.”

It is the first video marked as manipulated by Twitter since they announced such measures.

Trump later threatened to leave social media after again being flagged for misinformation, and in a separate instance had his account temporarily suspended.
